I am learning Esperanto.
For those who have never heard of this, or you think you have and you're pretty sure it's a caffeinated beverage: Esperanto is a constructed language, originally developed in the late 19th century with the intention that it be a universal second language, and the lofty ambition that it would thus foster peace and understanding throughout the world. That might be a bit much, but at least it would be a language with which everyone could understand each other, without anyone being forced to learn someone else's language.
